The AI-Native Universal Linter: Code Quality at Scale with AST Grep and LLMs

Coding standards are essential for maintaining code quality, consistency, readability, and maintainability. However, they often take a backseat due to tight deadlines and pressure to ship features quickly. Linters, static code analysis tools, have been the first line of defense against code quality issues but can be noisy and flag minor inconsistencies. AST Grep is a powerful tool that allows developers to write custom rules using regex-like queries to match code patterns and enforce coding standards. By combining AST Grep with Generative AI (Large Language Models), developers can gain deeper insights into the code's intent, discover potential issues, and suggest fixes based on best practices and coding standards. This approach reduces noise and provides more nuanced feedback compared to traditional linter rules. CodeRabbit is an AI-native Code Reviewer that leverages LLMs and AST Grep to improve developer productivity and code quality.
